Now, Conway wants someone to be held accountable. She fears Alfaro will just be classified as another opioid overdose because the leftover pills were thrown away.

"That was really keen on keeping those pills and having them tested so that we would know. But, no body's investigating it because they just view it as an overdose when it's not,” Conway said. “It is murder in every sense. Whoever's making these pills is murdering people.”

The coroner has not determined the cause of Alfaro's death. It'll take as long as four weeks for test results to prove fentanyl was in his system.
